In a setup we have two 4402 WLC with 16 AP, first 12 AP is get registered with WLC, remaining AP is not get register with second WLC, configuration for both WLC is same.
WLC Management address for fisrt one - 172.16.124.15/24
WLC Management address for second one - 172.16.124.17/24
when the first WLC is switched off second WLC is get registered with 12 AP, again when WLC one is switched on, the second WLC AP registration is going back to WLC one itself.
sh cdp neig detail show AP have got IP address, but why AP is not get registered with WLC...Please give me some suggestion,
